Next to nothing is known about this fellow, itís 10 inches in diameter and the multimeter is showing 3.3 Ohms resistance across the terminals, thereís a faint serial (?) number on the back which is 207142.

As Iím loth to leave a functional component without a purpose I began to think what sort of use I could put the sub toÖ

I recently undertook a £50 HiFi challenge which a friend set for me, I got him a setup comprising of an amp, bookshelf speakers and wiring for him to connect to his PC, I achieved this with a few quid to spare and he was very pleased with it, although after listening to my setup he expressed a desire for a bit more bass.

This leads me to my question;

Can I change this 10" car sub from a mobile bass provider to a house-bound boomer?

I know little about the intricacies of audio but as a Motorsport Engineering student Iím able to turn my hand to the practical side of assembly and manufacturing, besides, as the long nights draw in a new project will be another distraction to the never-ending deluge that is a British winter!

Is this an "El Cheapo" project?? a sub is a sub is a sub, probably not perfect but make a small box; whack in a cheap plate amp and see what it sounds like.
Probably sealed and don't forget the stuffing.
I have used car subs with mixed results and seems to depend more on crossover frequency than anything; try and keep it below 100 and hope the midbass is rolling off about there

If you can't get a hold of the T/S parameters and have no way of measuring them, it's a bit of a crapshoot. You could always try a box of about 1.5 cu ft and if it sounds boomy, add a bunch of insulation. If it sounds flat, add some wood or bricks to use up some of the volume. You'll need a plate amp. Probably around 75 watts should be OK.
